.TH slurmd "8" "Slurm Daemon" "February 2017" "Slurm Daemon"

.SH "NAME"
slurmd \- The compute node daemon for Slurm.

.SH "SYNOPSIS"
\fBslurmd\fR [\fIOPTIONS\fR...]

.SH "DESCRIPTION"
\fBslurmd\fR is the compute node daemon of Slurm. It monitors all tasks
running on the compute node , accepts work (tasks), launches tasks, and kills
running tasks upon request.
.TP
OPTIONS
.TP
\fB\-b\fR
Report node rebooted when daemon restarted. Used for testing purposes.

.TP
\fB\-c\fR
Clear system locks as needed. This may be required if \fBslurmd\fR terminated
abnormally.

.TP
\fB\-C\fR
Print actual hardware configuration and exit. The format of output is the same
as used in \fBslurm.conf\fR to describe a node's configuration plus it's uptime.

.TP
\fB\-d <file>\fR
Specify the fully qualified pathname to the \fBslurmstepd\fR program to be used
for shepherding user job steps. This can be useful for testing purposes.
.TP
\fB\-D\fR
Run slurmd in the foreground. Error and debug messages will be copied to stderr.
.TP
\fB\-f <file>\fR
Read configuration from the specified file. See \fBNOTES\fR below.
.TP
\fB\-h\fR
Help; print a brief summary of command options.
.TP
\fB\-L <file>\fR
Write log messages to the specified file.
.TP
\fB\-M\fR
Lock slurmd pages into system memory using mlockall (2) to disable
paging of the slurmd process. This may help in cases where nodes are
marked DOWN during periods of heavy swap activity. If the mlockall (2)
system call is not available, an error will be printed to the log
and slurmd will continue as normal.

.TP
\fB\-n <value>\fR
Set the daemon's nice value to the specified value, typically a negative number.
Also note the \fBPropagatePrioProcess\fR configuration parameter.

.TP
\fB\-N <hostname>\fR
Run the daemon with the given hostname. Used to emulate a larger system
with more than one slurmd daemon per node. Requires that Slurm be built using
the \-\-enable\-multiple\-slurmd configure option.

.TP
\fB\-v\fR
Verbose operation. Multiple \-v's increase verbosity.
.TP
\fB\-V\fR
Print version information and exit.

.SH "ENVIRONMENT VARIABLES"
The following environment variables can be used to override settings
compiled into slurmd.
.TP 20
\fBSLURM_CONF\fR
The location of the Slurm configuration file.  This is overridden by
explicitly naming a configuration file on the command line.

.SH "CORE FILE LOCATION"
If slurmd is started with the \fB\-D\fR option then the core file will be
written to the current working directory.
Otherwise if \fBSlurmdLogFile\fR is a fully qualified path name
(starting with a slash), the core file will be written to the same
directory as the log file.  Otherwise the core file will be written to
the \fBSlurmSpoolDir\fR directory, or "/var/tmp/" as a last resort. If
none of the above directories can be written, no core file will be
produced.

.SH "NOTES"
It may be useful to experiment with different \fBslurmd\fR specific
configuration parameters using a distinct configuration file
(e.g. timeouts).  However, this special configuration file will not be
used by the \fBslurmctld\fR daemon or the Slurm programs, unless you
specifically tell each of them to use it. If you desire changing
communication ports, the location of the temporary file system, or
other parameters used by other Slurm components, change the common
configuration file, \fBslurm.conf\fR.
